i have just noticed a glaring omission from your vintage emulations list!!!
Asynth by Antti at smartelectronix (also responsible for taurus, augur and cm's dominator synth)

easily up there in the top echelons of va's (including all payware emulations). some of the best antialiased oscillators i have heard and lots of lovely filters to choose from.
also arppe2600va is definitely worth a look. it's synthedit and a bit buggy but has a very nice filter and a great spring reverb. the mod matrix makes in an extremely powerful synth.
